Purpose: : 2-Amino-4,4α-dihydro- 4α,7-dimethyl-3H-phenoxazine-3-one (Phx) is known to have growth-inhibitory effects on various cell lines such as squamous cell carcinoma, adenocarcinoma and leukemia cell lines. In this study, we examined the efficacy of Phx on the proliferation of a human retinoblastoma cell line (Y-79) both in vitro and in vivo. Methods: : We evaluated the in vitro effect of Phx on the viability and apoptosis of Y-79 cells using MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide] assay. The effect of Phx on apoptosis of Y-79 cells was also evaluated by flow cytometry using annexin-V. The in vivo efficacy of subcutaneous injection of Phx was analyzed histopathologically in BALB/c nude mice inoculated subcutaneously with Y-79 cells. Results: : Phx inhibited the in vitro proliferation of Y-79 cells in a dose-dependent manner. The data obtained by flow cytometry suggest that the mechanism of proliferation inhibition is associated with apoptosis. In vivo, no ...
purpose. To characterize the molecular sequelae induced in retinoblastoma (Rb) cells by histone deacetylase inhibitors (HDACIs). Hydroxamic acid-based HDACIs such as vorinostat (suberoylanilide hydroxamic acid) induce the differentiation and apoptosis of transformed cells. Vorinostat has demonstrated significant anticancer activity against hematologic and solid tumors at doses well tolerated by patients and has been approved for the treatment of patients with cutaneous T-cell lymphoma.. methods. The authors evaluated the effects of the HDACIs vorinostat and m-carboxycinnamic acid bis-hydroxamide on the Rb cell lines Y79 and WERI-Rb1 with the use of the MTT assay, BrdU incorporation assay, flow cytometry, immunoblotting, gene-expression profiling, quantitative RT-PCR, and NF-κB DNA-binding assay.. results. Both HDACIs were effective against both Rb cell lines, inducing growth arrest and apoptosis in vitro. Vorinostat increased p53 expression and activated caspases -8, -9 and -3, whereas caspase ...
It has been proposed that the GAG-binding property of PEDF provides the molecular basis for its association with extracellular matrices and may serve to localize PEDF activity in the retina and CNS [14, 19]. However, the present results point to direct effects these polysaccharides might have on the biochemical interactions between PEDF and PEDF receptors on the surfaces of cells that respond to this neurotrophic factor. We have shown that the binding of PEDF to receptors in retinoblastoma cells is enhanced by the presence of extracellular heparin/HS-like GAGs, which can be found in the culture medium of retinoblastoma cells. The fact that the binding of PEDF to cell surfaces decreases with heparin/HS depletion, implies that heparin/HS molecules might act as cofactors for PEDF-receptor interactions. Interactions between PEDF and extracellular GAGs can also explain the complex formed by PEDF with CM even after protease treatment of the latter. The PEDF-heparin/HS complex may somehow facilitate ...
Background: Radiation is implicated in the induction of second malignancies in children with bilateral retinoblastoma. There is a need to determine whether this risk can be justified by good visual outcome when external beam radiotherapy (EBRT) is used as a salvage treatment.. Aim: To study the effectiveness of EBRT as a salvage treatment after failed primary chemotherapy and focal treatment in bilateral retinoblastoma.. Methods: This is a retrospective observational case series. The outcome measures after EBRT are: rate of eye preservation, rate of tumour control, visual potential, visual acuity, and radiation-induced side-effects.. Results: Thirty-six eyes (22 patients) were included. The median follow-up after EBRT was 40 months (19-165 months). Thirty-two eyes received lens-sparing radiotherapy and 4 received whole-eye radiation. The rate of eye preservation was 83.3% (30/36 eyes). Twenty-four eyes (66.6%) were controlled by EBRT and required no further treatment. Of the 30 preserved eyes, ...
Trilateral retinoblastoma is a syndrome consisting of bilateral (rarely unilateral) hereditary retinoblastoma in association with an intracranial neuroblastic tumour arising usually in the pineal region, infrequently at the suprasellar or parasellar region. It can arise from either hereditary or sporadic forms of retinoblastoma.

N2 - It has been reported that replacement of a functional retinoblastoma (RB) gene in RB defective WERI-27 retinoblastoma cells results in complete loss of their tumorigenic potential in nude mice following s.c. injection. We have repeated the identical studies and found that although tumors did not develop s.c, the RB reconstituted cells, either soon after RB virus infection or after long term cultivation, consistently produced tumors when injected intraocularly. These tumor cells, when reestab- lished in culture, were found to retain a normal RB protein as determined by direct Western blotting and immunocytochemical staining. The tu- mors, however, occurred with a longer average latency period and with less frequency compared to ...

To determine whether the retinoblastoma gene (Rb) localized at 13q14, might be the target of recessive mutations in lung cancer, eight primary SCLC tumors and 50 cell lines representing all major histologic types of lung cancer were examined with the Rb complementary DNA probe. Structural abnormalities within the Rb gene were observed in 1/8 (13%) primary SCLC tumors, 4/22 (18%) SCLC lines, and 1/4 (25%) pulmonary carcinoid lines (comparable to the 20 to 40% observed in retinoblastoma), but were not detected in other major types of lung cancer. Rb messenger RNA expression was ...
Pineoblastoma (also pinealoblastoma) is a malignant tumor of the pineal gland. A pineoblastoma is a supratentorial midline primitive neuroectodermal tumor. Pineoblastoma may occur in patients with hereditary uni- or bilateral retinoblastoma. When retinoblastoma patients present with pineoblastoma this is characterized as "trilateral retinoblastoma".[1] Prognosis of patients with trilateral retinoblastoma is dismal, only a few patients have survived more than 5 years after diagnosis; all survivors were diagnosed with small tumors in a subclinical stage.[2] Lately, this disease was featured in headlines of several newspapers all over the world in a patient without retinoblatoma.[3] ...
Retinoblastoma is caused by a gene mutation during cell division. In half of all retinoblastoma cases, there is no family history of eye cancer. However, if the gene mutation does run in the family, a childs chances of developing retinoblastoma increase substantially.. In most cases, children diagnosed with retinoblastoma are age 5 or younger, and it can occur as early as year 1. ...
The population of this prospective study included 23 consecutive children (11 males, 12 females). Patients ages ranged from 1 to 35 months (mean age, 11 months; median age, 9 months). Fifteen patients had unilateral retinoblastoma, and the remaining 8 had bilateral retinoblastoma. Patients clinical data were collected from inpatient and outpatient medical records of the referral center for retinoblastoma of our institution, including sex, age, affected eyes, and ophthalmoscopic data. Ultrasonographic data were available in 18 patients with 21 affected eyes. Three patients with bilateral retinoblastoma had already been submitted to enucleation of 1 eye before the admission to the department of ophthalmology. Parents gave informed consent for MR imaging and CT scanning in all the cases. The study protocol was approved by the ethics committee of our institution.. Two experienced ophthalmologists (T.H., S.D.F.) performed ophthalmoscopy, which always included careful examination of the ocular ...

N2 - Retinoblastoma was first described as a specific entity by James Wardrop in 1809, with enucleation as his suggested treatment. Histologic studies including those of Flexner and Verhoeff and subsequent electron microscopy have given insights into its pathogenesis. The establishment of cell lines of retinoblastoma, the "nude" mouse model, and other animal models have contributed additional information. Classic genetic and epidemiologic studies have led to a broad and intense interest in the tumor despite its relative infrequency.

Retinoblastoma is a rare cancer of the eye that typically affects children between birth and five years of age. The incidence of Retinoblastoma is one in 15,000 live births, with about 23 children being affected in Canada each year.. It is imperative that Retinoblastoma is diagnosed at an early stage. Some of the signs of Retinoblastoma include a white pupil, eye turn, or a wondering eye. An eye exam at 6 month of age and then age at 3 years of age (and every year after that) is recommended to rule-out Retinoblastoma.. Read More:. http://doctorsofoptometry.ca/retinoblastoma/. ...
Because of the hereditary nature of retinoblastoma, it is currently recommended that all siblings and children of retinoblastoma patients be examined under anesthesia (EUA) every 2 to 4 months during the first years of life. In the future, laboratory studies including karyotyping, Southern blot analysis, Polymerase Chain Reactions (PCR), DNA sequence analysis/polymorphisms, and Esterase D reactions may eliminate the need to examine children under anesthesia. The aim of genetic screening in families with hereditary retinoblastoma is to identify those persons who carry a mutation and are at risk for tumor development. In 15 percent of families with hereditary retinoblastoma, the tumor-predisposing mutation itself can be detected using karyotyping or Southern blot analysis. When a detectable deletion is present, one can identify individuals carrying the mutation with over 99 percent accuracy. In the remaining 85 percent of families, no mutation can be found directly. However, in 95 percent of such ...

As with any cancer, prognosis and long-term survival can vary greatly from child to child. Every child is unique and treatment and prognosis is structured around the childs needs. Prompt medical attention and aggressive therapy are important for the best prognosis.. Continuous follow-up care is essential for a child diagnosed with retinoblastoma. In hereditary retinoblastoma, new tumors may form in either eye until the child is 3 to 4 years old. Children will need very close follow-up by an ophthalmologist. Children with hereditary retinoblastoma and those treated with some chemotherapies, radiation therapies, and some other therapies, are at higher risk for new cancers later in life and should have regular medical and eye exams.

Retinoblastomas are typically diagnosed before their third year of life. For the next 2 years, most ophthalmic examinations are performed under anaesthesia. The risks of sedation requires the examiners be both quick and thorough.. We have found 3DUS to be uniquely valuable for evaluation of retinoblastomas. This is because 3DUS includes the ability to replay and reconstruct ultrasonograms in standard, oblique, and coronal views. Therefore, one main advantage of 3DUS (compared to 2DUS) is that it allows for multiple interactive reviews of reconstructed ocular volumes (without patient contact or anaesthesia). It also allowed for the first ultrasound generated coronal views of the optic nerve.. These unique 3DUS capabilities become even more important when one considers the findings that have been associated with an increased risk for metastasis: tumour contact with the choroid, optic nerve invasion, and extrascleral extension.16 Unlike standard two dimensional ultrasound (2DUS), 3DUS offers the ...

Retinoblastoma (RB) is an intraocular cancer that affects young children. There is an ongoing effort to find new agents for RB management that are effective, specific and with few side-effects. In the present study, we tested artesunate (ART), a synthetic derivative from the herbal drug artemisinin, used in the clinic for the treatment of malaria. We analyzed ART cytotoxicity in an RB cell line (RB-Y79) and in a retinal epithelial cell line (hTERT-RPE1) by flow cytometric analysis (FCM). We related the effect of ART to the expression of transferrin receptor 1 (TfR-1, also known as CD71) by knocking down CD71 with RNAi and analyzing cell cycle variables by FCM. We found that the cytotoxic action of ART is specific for RB cells in a dose-dependent manner, with low toxicity in normal retina cells. ART is more effective in RB than carboplatin with a markedly strong cytotoxic effect on carboplatin-resistant RB cells. RB had higher CD71 levels at the membrane compared to normal retinal cells. We ...

Retinoblastoma (RTB) is the most frequent tumour of the eye in early childhood and the commonest cancer in the first year of life. Approximately 60% of cases are sporadic and unilateral. Unilateral tumours are usually diagnosed in the advanced intraocular stage and the most frequent treatment prescribed is enucleation. This prevents disease progression but has an important visual risk, and also constitutes a mutilation, with potentially devastating psychological effects on patients and their relatives.. At diagnosis, patients affected with RTB and their relatives are faced with the important effects of this disease, such as a threat to life, although rare in developed countries, and the risk of losing their sight, which depends on the uni- or bilateral nature of the tumour, the topography of the tumour or tumours, and the still prevalent need for enucleation as a treatment. In fact, almost all advanced stage unilateral RTBs are treated with enucleation. In addition to the risk to life and the ...

N2 - X-arrestin (arrestin-3) is an arrestin present specifically in the outer segments of red-, green-, and blue-cone photoreceptors. The X-arrestin gene is on Xcen-q22, and consists of 17 exons with a promoter containing a TATA box and elements important for photoreceptor expression, including three CRX and one PCE-1-like element. In order to delineate the promoter structure necessary for the pan-cone-specific expression of X-arrestin, the expression of the gene in retinoblastoma cell lines was investigated, and a structure-function analysis of the promoter was conducted in the appropriate cellular substrate. Expression of X-arrestin was detected at a low level in the Y79 retinoblastoma cell ...
Patients with familial/heritable retinoblastoma (RB) are at increased risk of developing second malignancies throughout life, including a pineoblastoma (trilateral RB [TRB]) in early childhood. Current guidelines recommend regular surveillance brain imaging for those with heritable RB until 5 years of age. The presence of pineal cysts has been reported in patients with RB. Pineal cysts are thought to arise due to focal degeneration of the pineal gland and can be found incidentally. The finding of pineal abnormalities including cysts in children with RB on imaging is disconcerting, as it raises the possibility of an underlying malignancy, specifically a pinealoblastoma ...
Three patients with late recurrence of retinoblastoma were seen, which count for less than 0.01%. All of them were bilateral diseased at the time of first diagnosis, and underwent an enucleation of one eye by initial treatment. Considering the eye of recurrence retinoblastoma, all initial retinoblastomas were categorized in a different ICRB group and therefore underwent a different initial therapy. Patient 1 had an ICRB-A retinoblastoma wherefore laser- and cryocoagulation therapy was done. Patient 2 had an ICRB-D retinoblastoma and underwent 6 cycles of systemic chemotherapy. Patient 3 had an ICRB-D wherefore a percutaneous radiation therapy was done. Al tumours were inactive after first treatment. After respectively 5, 6 and 3 years of inactivity, in all of these patients a recurrence of the retinoblastoma was seen. This late recurrence was treated different in all patients: Patient 1 was treated with 6 times of intravitreal Melphalan injection and radiation therapy with Ruthenium, patient 2 ...
For Lovell resident Patrick Moen, 26, cancer was life threatening, but ultimately turned out to be life changing, too. Moen was diagnosed with bilateral retinoblastoma at only six months old. As a result, he doesnt know what its like not to have cancer. He also doesnt remember what it was like to have vision because the disease rendered him blind in both eyes at an early age.. In spite of what some might see as a disability, Moen said he sees it as something that adds purpose to his life. That purpose is to inspire others on a spiritual level. His story is one of hope and faith.. According to the National Cancer Institute, retinoblastoma is relatively uncommon and accounts for about 3 percent of the cancers occurring in children younger than 15 years of age. The estimated annual incidence in the United States is approximately four cases per 1 million in children younger than 15 years old. Although retinoblastoma may occur at any age, it most often occurs in younger children, up to 4 years ...
10-year-old child was seen in the office on August 6, 2008.

Scientists have developed a new locally applied treatment for retinoblastoma, a childhood cancer of the eye arising from immature retinal cells in one or both eyes and can developed from anytime between gestation until up to 5 years of age. This relatively uncommon condition affects about 1 out of every 15,000 live births, or about 250-300 children in the US each year.. Based on the theory that a molecule called MDMX prevents apoptosis or programmed cell death in retinoblastoma cancer, scientists used a combination of nutlin-3, which blocks MDMX and topotecan, another retinoblastoma drug candidate. Local delivery of the two-drug combo was found to be effective, reducing tumor size significantly more than the most effective known combination of standard chemotherapy drugslinks.. "Our finding with locally applied nutlin-3 also has major implications for certain forms of adult cancers, since some forms of breast, lung, prostate and colon cancer are caused by abnormally large quantities of MDMX," ...

Retinoblastoma is a rare cancer of the retina of the eye. The retina is in the back of the eye. Its the part of the eye that receives light. Retinoblastoma is the most common tumor affecting the eye in children. It almost always occurs in children less than 5 years old.
Retinoblastoma is caused by a mutation in a gene that controls how cells divide. As a result, cells grow out of control and become cancerous.. In about half the cases, this mutation develops in a child whose family has never had eye cancer. In other cases, the mutation occurs in several family members. If the mutation runs in the family, there is a 50% chance that an affected persons children will also have the mutation. These children will therefore have a high risk of developing retinoblastoma themselves.. The cancer most often affects children younger than 7 years old. It is most commonly diagnosed in children 1 to 2 years old. ...

Retinoblastoma, the most common childhood intraocular tumor has complex genetic basis of cancer development, initiated by biallelic inactivation of RB1 gene [28]. Genetic testing of RB1 will be beneficial to provide counselling for families. However, genetic analysis of heterogeneous spectrum of variants in RB1 gene is no trivial task [4] and essentially requires comprehensive approach. Here, we have used NGS approach for the molecular analysis of Indian patients with RB, based on RB1 gene target enrichment, multiplexing and bioinformatics pipeline. We used in-house pipeline to successfully detect both pathogenic germline and somatic variants in RB patients. With our approach, we were able to identify heterogeneous spectrum of RB1 gene variants including SNVs, InDels and CNVs. All the variants detected were validated using Sanger sequencing, MLPA and size fractionation methods. Thus, our approach, achieving a diagnostic rate of 85%, proved to be efficient for the molecular diagnosis of RB. ...
A retinoblastoma is a rare malignant tumor of the retina. It occurs as both hereditary and non-hereditary forms. It is seen typically in children who are below the age of 5 years.
Researchers have found a non-invasive way to biopsy retinoblastoma tumors, which could enable precision therapies for children with the rare cancer.

Cancer occurring in infants often has a clinical and biological behavior that is different from cancers occurring in older children. The histological distribution of cancers in infants is different from that in older children. The five most common types of cancer occurring in infants in Taiwan are leukemia, neuroblastoma, germ cell tumors, central nervous system neoplasms, and retinoblastomas. Cancer in infants represents a unique situation in which to study cancer etiology. A significant number of infants with cancer have a genetic susceptibility to the disease; however, some emerging studies suggest a potential role for environmental, dietary, and drug exposures in the etiology of infant cancers. Further definitive trials will be necessary to establish clear associations, however. Because of their very young age and the immaturity of many of their physiological systems, the approach to treatment in young infants differs from that in older children. The infants response to treatment also differs from
